There are several steps you need to follow when you install the SCM.
Identify the carton holding the SCM and remove it from that carton.
1.
See Section 2.3.
Set jumpers on the SCM based on whether your external DC bulk
2.
power supply provides +12V or +6V. See Section 2.5.3.
If your SCM includes a mode switch (SW1) set it according to
3.
Section 2.5.4.
Slide the SCM into slot #1 of the housing.
4.
Unplug terminal block connector TB1 from the SCM and wire it to
5.
an external bulk DC power supply. See Section 2.5.6.

6.
and wire it to an RTD according to instructions in Section 3.7.
After you configure and install the CPU module in slot #2 re-connect
7.
terminal blocks to their connectors to apply power to the unit.
The SCM has five jumpers (JP5, JP6, JP7, JP8, JP9) which you set
based on whether your bulk DC power supply will provide +12V or
+6V. See Figure 2-12 to locate the jumpers on your version of the
SCM.
 JP5, JP6, JP7, JP8 and JP9: Three-position bulk power system
selection Jumper:
o 1-to-2 Installed = Choose this to select +12V Bulk System
o 2-to-3 Installed = Choose this to select +6V Bulk System
The SCM has a DIP switch that controls whether the SCM operates in
Local Mode or Recovery Mode.
Local Mode is the normal operating mode for the ControlWave EFM,
and is the factory default. We recommend you use the factory default
unless you have a reason to use Recovery Mode.
Only use Recovery Mode during system firmware upgrades or core
updumps. See Chapter 5 for more information on these subjects.
